Created in Belize · Ready internationally
One product, configured for the election environment in front of you.
Cesium originated in Belize and reflects the realities of field-led election and campaign operations. It is not locked to Belizean structures: Silvatech can configure the geography, terminology, roles, voter-file fields, permissions, reports, languages, and operating procedures for teams in other countries.
Discuss Cesium for your countryLocal structures
Map constituencies, districts, divisions, wards, precincts, municipalities, or the equivalent operating areas in your country.
Local workflows
Configure role names, approvals, reports, languages, field procedures, and command views around the way your team works.
Private deployment
Scope hosting, access controls, imports, support, and data boundaries for each customer and jurisdiction.
International readiness is not a one-size-fits-all claim. Every deployment begins with discovery, data mapping, and a review of local operational and legal requirements.
Public demo access
Explore a safe, isolated Cesium workspace.
Every voter, event, report, notification, and import is synthetic. Demo changes are simulated in the browser and are not connected to customer systems or persisted.

Private by design

Role and polling-area access controls
Users receive access based on their approved role and operating scope.
Per-instance secrets
Deployment credentials and configuration stay inside each customer boundary.
Authenticated live updates
HTTPS and authenticated realtime updates support operational workflows.
Audit and import history
Administrators can review important actions and import processing history.

FAQ
Common Cesium questions
Can Cesium be configured for elections outside Belize?
Yes. Cesium originated in Belize, but its geographic structures, terminology, roles, voter-file fields, permissions, reports, languages, and workflows can be configured for private election and campaign operations in other countries. Each deployment starts with discovery and a review of local operational and legal requirements.
Can two organizations use Cesium for the same area?
Yes. Each contracted organization receives a separate environment, data boundary, secrets, users, and domain configuration.
Can Cesium support municipalities?
Yes. A municipality can operate within the relevant polling areas of a parent electoral division while retaining its own administrative scope.
Can we bring our Excel voter file?
Yes. Cesium supports Excel imports, validation, duplicate handling, review of exceptions, and operator-friendly processing history.
Can clerks use phones and tablets?
Yes. Field workflows are designed for phones and tablets, while command and administrative views use the additional space available on larger screens.
Is each deployment private?
Yes. Customer deployments are separately configured with their own environment, data, access controls, secrets, and operational boundary.
What support is available on election day?
Silvatech can scope launch checks, monitoring, standby support, issue triage, and post-event reporting around the needs of the organization.
